" Let it never be said that we cannot know whether a Christian really loves Christ. It can be known. It can be discovered. The proof can be seen. You have heard them this very day. Love to the Lord Jesus Christ is no hidden, secret, unseen thing. It is like the light – it will be seen. It is like sound – it will be heard. It is like heat – it will be felt. Where it exists, it cannot be hidden. Where it cannot be seen, you can be sure there is none. "
